freqtoint {emuR}

Function to find the column number corresponding to frequencies of a spectral object

Description

Find the column number corresponding to frequencies of a spectral object.

Usage

freqtoint(trackdata, j)

Arguments

trackdata

A spectral object

j

A vector of frequencies

Details

This function is used in conjunction with object oriented programming of EMU spectral objects. It should not in general be called from inside a function. Its principal use is to determine the column number(s) corresponding to frequencies for spectral trackdata objects or spectral matrices or the element number for spectral vectors.

Examples

freqtoint(fric.dft,1000:2000)
# all frequencies except 1000-2000
freqtoint(vowlax.dft.5, -(1000:2000))
# all frequencies except 1000 Hz
freqtoint(e.dft, -1000)
# the d.c. offset - i.e. column 1
freqtoint(vowlax.dft.5, 0)
# all freqs except the d.c. offset - i.e. not column 1
freqtoint(vowlax.dft.5, -1)
